STR-W6252D中文资料Power IC for PWM Type Switching Power Supply with Low Noise and Low Standby Power数据手册Sanken规格书

描述 Description

■General Descriptions
The  STR-W6200D  series  products  are  power  ICs  for  switching  power  supplies, incorporating  a  power  MOSFET  and  a  current-mode  type  PWM  controller  IC.  The  low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load condition. The product achieves high cost-performance power supply systems with fewexternal components.■

特性 Features

Current-Mode Type PWM Control
PWM with Jittering Function
  The function reduces the EMI noise and enables simplified (low-cost) EMI filters. 
  The jittering period is adjustable by an external capacitor.
Auto-Standby Function
  The burst-oscillation enables the low standby power. 
  Input Power PIN< 100mW at no load
Built-in Startup Circuit, enabling low power consumption
Overcurrent Protection (OCP) with Built-in Input Compensation Circuit
  The function has less AC input voltage dependency.
Overload Protection (OLP) with Built-in Delay Timer( the delay time is adjustable by an external capacitor)
External Latch Protection (ELP)
   The function enables the latch shutdown by externalsignal.
Bias-Assist Function, reducing operating VCC voltage drop
  The function improves the startup operation and makes a low VCC capacitor applicable.
Leading Edge Blanking Function
Slope Compensation Function
Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
Various Protections
 Overcurrent Protection (OCP)---------------------------------- Pulse-by-Pulse
 Overload Protection (OLP) ------------------------------------- Auto-Restart

Switching Power Supplies for Home  Appliances  (White  Goods),  Digital  Consumer  Equipment,  OA  Equipment,  Industry  Machines, Communication Devices, Others

简介

STR-W6252D属于集成电路（IC）的ACDC转换器离线开关。由制造生产的STR-W6252DAC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
